63 door latch?

[70 net440]

So, I've been fighting the driver side door latch in the Wife's '63 for years now. I've replaced the latch a few times, had body shops try to adjust it, and it still won't latch unless it's slammed hard. My friend at the body shop says I need a new striker as well as a new latch. I'm waiting for a backorderd latch and no one seems to make the striker. I figure any I find will be a 45 year old POS like I already have. So, I'm thinking about the bear claw latches they use in street rods. Anyone using them? How hard are they to install?
